The combination of classes you’ve chosen is extremely rigorous and I personally think it is not a good idea to take five AP classes and two honors classes while keeping up with your EC activities. Depending on the quality of the teacher, your past track record, and your academic strengths the schedule is doable, but not advisable. AP Chem is a lot of work and is the only non A that my daughter has received in her entire academic career. She ended up with an A- in the class and a 4 on the exam. AP Calc BC is also a more difficult class as it begins to tackle some more theoretical aspects of arithmetic. The other AP classes are not necessarily difficult but you should be prepared for a lot of work and there are only 24 hours in a day.
